(a)
To find: Name of two points that are collinear with P.
(a)

Answer to Problem 55E
Point K and point N are collinear with P.
Explanation of Solution
Given information: The data is given in following figures:
Calculation: In the given figure, we can see that point K and point N are in the same line as in point P.
Hence, point K and N are collinear with point P.
(b)
To find: Name of two planes that contain J.
(b)

Answer to Problem 55E
Planes JKL and QNK contain point J.
Explanation of Solution
Given information: The data is given in following figures:
Calculation: In the given figure, we can see that point J lies in planes JKL and QNK.
Hence, planes JKL and QNK contain point J.
(c)
To find: Name the points that are in more than one plane.
(c)

Answer to Problem 55E
Every point shown in figure is in at least two planes.
Explanation of Solution
Given information: The data is given in following figures:
Calculation: In the given figure, we can see that each point lies in more than one plane.
Therefore, each and every point shown in figure is in at least two planes.

Thank you.arrow_forwardEvaluate the line integral sin z dz, So sin where C is the portion of the curve y = x² from 0 to −1 + i.arrow_forwardLet f(z) be complex differentiable everywhere in C. Fix two distinct complex numbers a and b and a circle C of radius R with |a| < R,|b| < R traversed in the counter-clockwise direction. Evaluate the integral Sc − f(z)dz (z - a)(z – b) in terms of a, b and the values of f at those points.arrow_forward
- Temperature measurements are based on the transfer of heat between the sensor of a measuring device (such as an ordinary thermometer or the gasket of a thermocouple) and the medium whose temperature is to be measured. Once the sensor or thermometer is brought into contact with the medium, the sensor quickly receives (or loses, if warmer) heat and reaches thermal equilibrium with the medium. At that point the medium and the sensor are at the same temperature. The time required for thermal equilibrium to be established can vary from a fraction of a second to several minutes. Due to its small size and high conductivity it can be assumed that the sensor is at a uniform temperature at all times, and Newton's cooling law is applicable. Thermocouples are commonly used to measure the temperature of gas streams. The characteristics of the thermocouple junction and the gas stream are such that λ = hA/mc 0.02s-1. Initially, the thermocouple junction is at a temperature Ti and the gas stream at…arrow_forward3) Recall that the power set of a set A is the set of all subsets of A: PA = {S: SC A}.
